HI have the same issue with 6 items.... I ran a compare against one item and it's duplicate and the only thing different between the two desktops were the s/n. One had the real sn and the other had the netbios name.

I've looked through Dan's information, and what I found is that our scanner doesn't have a record of the original device (the ones with a serial number not the netbios name).

If you open the file log/finder_child.log in your installation directory, and go to the end of the file, you will see a listing in the "known computers" for the scanner. If your duplicated devices both show up, this is a scanner issue that still needs to be addressed and I would need your help debugging. If they don't show up in the scanners log, this would then be an issue that we don't know about that probably occurred when the scanner tried to alias the old duplicate to the new duplicate. If you want to help me track this down, I would need information from your 2.x installation so I can track down what went wrong.

I have also had this problem in every version of SW I have used. I usually just curse after every major scan and manually delete the duplicates.

Sorry about that David. We have been trying to improve this part and remain backwards compatible without always being successful. In any case, if you haven't added hand edited data or tickets to either the old or new duplicates, if you delete all instances of them, the duplicate problem should go away. If it doesn't, we still have work to do and I could then use your help into figuring out what we are still doing wrong.
